Hi Kumar and all,

First let me introduce myself. My name is Huang Chunxing and I'm a backplane 
engineer from Huawei.

I have read your AMI proposal to IBIS macro model task group. It's a great idea 
to solve that IBIS couldn't handle the DSP algorithm problems. In the paper, I 
noticed that AMI also need to meet the requirement of proprietary 
post-processing of data. I totally agree that.

In my opinion, the error propagation of DFE is very good case for this. One 
error bit of DFE will effectively change the error probability of sequential 
bits, depending on the DFE taps and coefficients. If we want to analyse the DFE 
error propagation effect, we need to know the coefficients of DFE. But I didn't 
find any output params of the defined ami functions related to it, including 
AMI_init and AMI_getwave. In order to keep the IBIS with most updated DSP 
algorithm, some extra user defined params may be required. I hope you and group 
member will consider my suggestion. By the way, I know little about dll. If my 
understanding is wrong, I apologize first. Thanks!
